RADIATOR.

`Application filed May 17, 1924. Serial No. 713,882.

To all 'whom it may concern:

Be it known that I. JOHN KARMAZIN, a citizen of the United States,residing in Detroit, county of Wayne, State of Michigan, have inventedcertain new and ,useful Improvements in Radiators, of which thefollowing is a specification.

This invention relates to radiators, and is illustrated in the drawingsandwill be herein described as applied-to a radiator of the typedisclosed in my prior copending application Sr. No. 579,416, tiledAugust 3, 1922. The radiator described in said application comprises anumber of horizontally disposed tin forming elements` each havingintegral therewith tapering tubular projections which telescope into theopen ends of similar tubular projections on the next lower element,thereby forming a plurality of tubes extending vertically from top t0bottom of the radiator. The tubes on the bottom'element extend into4 thelower header and water circulates thru the tubes from the upper to thevlower header.

It will be seen that in this construction, which. is more fullydescribedin my application above mentioned, the space surrounding the tubesprojecting from the bottom element into the lower header rforms a trapor ocket in which steam may accumulate.

ne object of the' 'present invention is tol provide a radiator of thetype described with means for preventing such accumulation of steam inthe lower header.

A further object of this invention is to provide a radiator with meansin communication with Athe top of the lower header for permitting theescape'o-' steamtherefrom.`

A further object of this invention is to provide a radiator comprisingwater circu- .lating tubes with specially constructed steam escapetubes.

A further ob'ect of this invention is to provide a ,radiator comprisingan upper headerI and a lower header, with two sets of tubes extendingbetween the headers, the

`tubes of onel set terminating at a Vdierent level in one or both ofsaid chambers from the tubes of the other set.

A further object of this invention is to provide a radiator comprisingtubes extending between upper and lower chambers or headers withauxiliar. devices associated i withk certain of said tu es andprojecting into said upper chamber.

With these and other objects in view my in the drawings, and Ato behereinafter de-` scribed. f

In the drawings:

Figure 1 is a vertical section of a radiator embodying my invention.

Figure 2 is a detail elevation in section showing an auxiliary tubeextending into the upper header. i

Figure 3 is a detail elevation in section showing a modified form of myinvention.

The radiator to which I have applied my invention for purposes ofillustrationy comprises a plurality of tin forming elements 10, eachformed with a plurality 'of tapering tubular projections 11, surroundedby perforations in the tins, the projectionsaof one element extending ashort distance into the projections on the next lower element, therebyforming continuous tubes extending from the upper header or chamber 13to the lower header or chamber 12. The upper chamber comprises a curvedtop well 14 and is closed by cap 141. For the purpose of securing propercirculation of air about the water tubes the intermediate elements 10,are perforated as shown at 15 (Figure 2). The top element 101 forms thebottom of the upper chamber, while the bottom element 102 forms the topof the lower chamber.

The construction thus far described is substantially similar to thatdisclosed in my prior co-pending applicationl above identified. It willbe seen that the projections 1l. on the bottom elementl 102 extend ashort distance into the lower chamber. Steam formed from the circulatingwater may rise into the space surrounding these tubes, accumulate thereand retard the circulation and cooling of the water in the radiator, andthe radiation of heat from the lower header. For the purpose ofpreventing such accumulation of steam and permitting escape of the steamfrom the top of the lower chamber to the upper chamber, the followingdevices are provided.

In the form of my invention illustrated in Figures 1 and 2 the bottomelement 102 is specially formed, certain ot the projections 11 are cutott, leaving pertorations 16,

or the element is formed with perforations This forms a plurality ofopenings flush with the top of the lower header so that `the steamcannot pocket'between the y top. of

this header and the bottom of the tubes 11D projecting thereinto butmayescape into the tubes 17 which communicate with the openings 16 and riseto the upper header.

To facilitate the delivery of the steam risl ing through the specialtubes 17 to the upper chamber, said tubes may be provided at theirikupper ends with tubular extensions, 18, ,j which project above thenormal water level in the upper header, and preventI the water fromflowing downward therethrough. These extensions are preferably formedseparately, inserted into the special tubes 17 Y and secured thereto byany? desired means.

described and illust-rated in the drawingsbut is to be construed asextending to all" equivalent devices falling within the scope oftheappended claims.

I. claim: Y. f v 1. A radiator comprising a lower chamber and an upperchamber, the bottom wall of the upper chamber and the top wall of thelower chamber each being flat and two sets of tubes extending betweensaid chambersI and projecting therein and terminating re- L spectivelyat different levels in each chamber.

2. A radiator including a lower chamber having water circulating meansprojecting therein, and other means connectedtherewith and terminatingflush ,with the wall thereof and extending to a point above the Anormalwater level of the radiator whereby the escape of steam is permitted.

3. A radiator element comprising perfora# tions surrounded by tubularprojections and adapted to-receive the freey ends of'similar tubularprojections, and other perforations adapted to receive the free ends oftubular project-ions but not surrounded by tubular projections.

4. A radiator comprising a pair of charnbers, tubes connecting saidchambers andi projecting into one of said chambers, while terminatingflush with the/.walls of the otherl chamber and other tubes connectingsaid chambers and projecting into the other of said chambers whileterminating flush with the wall of the first chamber. y

- 5. A radiatorcomprising an upper chamber and a lowerchamber, tubesconnecting said chambers'and-'terminating flush with .the wall of theupper chamber and projecting into said lower chamber, and other tubesconnecting said -chamber and terminating Hush with the wall of the`lower chamber and projecting into saidyupper chamber.

6. A radiator comprising an upper cha-mber, a lower chamber, tubes'extending between said chambers and tube extensions applied to certainof said tubes and extending into said upper chamber.

7. In a radiator of the type described an upper header, a lower header,a plurality of tubular passages extending from the upper header to thelower header and terminating at different levels, the tubes of one leveladapted to conduct a liquid 'in one direction between the headers and`the tubesj of the other level adapted to conduct a gaseous fluid in theother direction.

8. The method of venting a radiator of the type inv which the watertubes project into the lower header which-comprises permitting steam orthe* like to escape from the- 'top of the lower. header to a-point abovethe normal water level of the radiator.

9. A radiator of the type described comprising an upper chamber, a lowerchaiilber,

and a core comprising a plurality of` fin members with integral tubular.projections `extending in the lsame direction. therefrom, the tubularprojections. of one iin extending into the tubular projections of theadjacent fin to formwater conduitsthrough-tlie core and the, tubularprojections of the. .terminal lin projecting into one of said chambers,and

means terminatingflush with thel wall of. said chamber .for permittingthe escape. of,

ste-am therefrom. f
